CYLINDER-BODY FOR CONTAINERS.

Specification of Letters Patent. Patentedtl ct. 3f, rare.

Application filed April 12, 1913. Serial No. 760,592;

To all whom it may concern:

Be it known that I, MAURICE LACHMAN, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have in vented certain new and useful Improve ments in Cylinder-l3odies for Containers, of which the following is a specification.

My present invention relates in general to kegs, barrels and other similar forms of containers for use in shipping fruit, flour and other miscellaneous goods and articles of merchandise.

The invention more particularly relates to the construction of the cylindrical body for such containers.

The object of the invention is to provide a container as a substitute for those heretofore made of wood and to these ends to construct the cylindrical body portion, to which part this invention relates, mainly of paper, straw-board or other paper-like material.

In carrying out the object of the invention the paper cylinder is provided on either or both of its surfaces with a thin coating of sheet metal. The paper forms the strength and rigidity of the container while the metal merely serves to protect the paper from moisture, tears or other ill use which affects the paper when its surface is, as has been heretofore proposed, directly exposed.

The invention consists in the new and novel construction of cylinder for containers hereinafter more particularly described and then specified in the claims.

In the accompanying drawings, Figure 1 is a longitudinal section through a container cylinder in accordance with this invention. Fig. 2 is a horizontal transverse section through the same. Fig. 3 is a longitudinal section through a similar structure, the metal coating being provided only on the outer surface of the cylinder.

'1 indicates a cylinder made of paper, straw-board or other paper-like material and preferably consists of a considerable number of layers of paper superimposed one on the other and firmly united together under pressure by a suitable adhesive, the whole when completed forming a very solid, strong and rigid wall. The particular manner of forming the paper cylinder 1 forms no part of this invention and it will be understood that any cylinder of paper whose walls are thick and rigid might be employed, such structures per 86 being now well known in the art. The paper cylinder 1 provides all the strength and rigidity necessary for the container, the metal coating, to be presently d'escribechbeing pro vided merely for protection to the paper. 2 indicates a metal'sheet exceedingly thin in cross-section and applied to the outer surface of the cylinder 1'. The metal sheet being merely for protection and not for strength may be of the thinnest metal, 30 or even 40 gage being preferred. This metal sheet when thin as described is applied under pressure to the surface of the cylinder, so that it forms a coating therefor, by means of an adhesive preferably consisting of a mixture of silicate of soda and rosin or other resinous compound oreferably mixed together in equal quantities and rendered into a plastic or liquid state.

It has been found in the past that adhesives heretofore proposed, such as glue,

cement, &c., have failed to properly secure metal to paper but I find that by employing the adhesive substance as above specified that the metal becomes united with the whole surface of the paper so that it practically becomes a unit therewith and at all times remains so. If the. metal coating is not united in this manner with the paper, the combination'is of little or no value for practical purposes.

If desired a sheet metal coating as above described may be provided on the outer surface only as illustrated in Fig. 3 or on the inner surface of'the cylinder 1 or on both surfaces as shown in Fig. 1, the inner coating being. indicated at 3 in this figure.

.By so providing a paper cylinder which will give the necessary strength and rigidity to the container with a sheet metal coating united firmly and positively with it over its whole surface, a body portion is attained which is vastly superior to one made of wood or entirely of metal in that it has all the advantages of an all-metal one without the expense or weight.

It will be understood that to complete the container ready for shipping goods, suitable heads are provided at each end properly secured to the cylindrical'body. These features being so well understood in the art and forming no part of this invention, description thereof is deemed unnecessary and is accordingly dispensed with.

What I claim as my invention is:

i 1. A container comprising a cylindrical ing united with said cylinder over the entire surface of the Wall thereof, and an adhesive including silicate of soda and rosin comprising a means for uniting said paper cylinder and metal coating.

Signed at New York in the county of New York and State of New York this 10th day I of April, A. D. 1913.

MAURICE LACHMAN.
